获取Python中特定JSON元素的值 [英] Get the value of specific JSON element in Python

问题描述

我是Python和JSON的新手，所以如果我听起来一无所知，我们深感抱歉.我从Google Translate API获得以下结果，并想解析出"translatedText"的值:

I'm new to Python and JSON, so I'm sorry if I sound clueless. I'm getting the following result from the Google Translate API and want to parse out the value of "translatedText":

{
 "data": {
  "translations": [
   {
    "translatedText": "Toute votre base sont appartiennent à nous"
   }
  ]
 }
}

使用以下命令将此响应简单地存储为字符串:

This response is simply stored as a string using this:

response = urllib2.urlopen(translateUrl)
translateResponse = response.read()

是的，我要做的就是获取翻译后的文本并将其存储在变量中.我已经搜索过Python文档，但它看起来如此令人困惑，而且似乎没有考虑将JSON存储为简单字符串而不是一些超酷的JSON对象.

So yeah, all I want to do is get the translated text and store it in a variable. I've searched the Python Docs but it seems so confusing and doesn't seem to consider JSON stored as a simple string rather than some super cool JSON object.

推荐答案

您可以使用Python> = 2.6中的json模块将文本解析为对象:

You can parse the text into an object using the json module in Python >= 2.6:

>>> import json
>>> translation = json.loads("""{
...  "data": {
...   "translations": [
...    {
...     "translatedText": "Toute votre base sont appartiennent  nous"
...    },
...    {
...     "translate": "¡Qué bien!"
...    }
...   ]
...  }
... }
... """)
>>> translation
{u'data': {u'translations': [{u'translatedText': u'Toute votre base sont appartiennent  nous'}]}}
>>> translation[u'data'][u'translations'][0][u'translatedText']
u'Toute votre base sont appartiennent  nous'
>>> translation[u'data'][u'translations'][1][u'translate']
u'¡Qué bien!'
